The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1 and Figure 2, comprise a frame, lowering or hoisting gear, the front end of desktop (1) is movably connected on the frame (2) by loose-leaf, and tooth bar (5) is housed on the desktop (1), and tooth bar (5) flexibly connects with the reclining apparatus that has gear (7).
Best mode of the present utility model is to be provided with support bar (3), (4) and tooth bar (5) on table frame (2), and an end of support bar (3) and (4) flexibly connects with desktop (1) and table frame (2) respectively, and the other end is connected by movable axis (6) with tooth bar (5); Reclining apparatus is made up of self-locking knob (8), travelling gear (10), lifter wheel (11) and the chain (12) of band concentric gear (9), pinion (13) is housed on the travelling gear (10) with one heart, chain (12) is connected on the pinion (13) and lifter wheel (11) of travelling gear (10), concentric gear (9) and travelling gear (10) engagement; Gear (7) is housed on the lifter wheel (11) with one heart, and gear (7) meshes with the latch of tooth bar (5); Tooth bar (5) is contained in desktop (1) both sides, lower end, connects by power transmission shaft (14) between two tooth bars (5); Reclining apparatus also can change chain drive into the alternate manner transmission, specifically is travelling gear (10) is connected by belt or rope with lifter wheel (11); On the feet of table frame (2) lowering or hoisting gear (15) is housed; As shown in Figure 3, lowering or hoisting gear (15) is for passing interior (16) of a pin, a power transmission shaft (18) is equipped with at outer tube (17) two ends, power transmission shaft (18) two ends have the gear teeth (19), wherein an end also is provided with braking tongue (20), the gear teeth on the power transmission shaft (19) are meshed with tooth bar (21) on the interior pipe (16), braking tongue (20) on the power transmission shaft is inserted in the groove of unblanking (22) of turning knob, turning knob is had the knob head (24) of groove of unblanking (22) and fixed groove (23) by two ends, braking sleeve envelope (25), knob handle (26), two blocks of semicircle brake(-holder) blocks (27), (28) and trig loop (29) form, braking sleeve envelope (25) is enclosed within on the knob head (24), the fixed groove (23) of knob head (24) one ends is inserted in the steady pin (30) of knob handle (26), the groove of unblanking (22) of the other end snaps in two blocks of semicircle brake(-holder) blocks (27), (28) back is locked by trig loop (29), and is fixed on the outer tube (17); As Fig. 6, shown in Figure 7, the straight line of semicircle brake(-holder) block (27), (28) is provided with hook and stumbles (34), hook stumble (34) be stuck in the groove of unblanking (22) of knob head (24), as shown in Figure 5; Bearing 31,32 and 33 is equipped with at the two ends of turning cylinder (18) upper exterior tube.
During use, the knob handle (26) of rotating lifting gear, brake(-holder) block hook stumble (34) clamp braking tongue (20) and drive power transmission shaft (18) and rotate, thereby make the gear teeth (19) drive tooth bar (21) oscilaltion.Because the diameter of semicircle brake(-holder) block is bigger, and braking tongue (20) diameter is very little, therefore cause the moment great disparity, and the table body can't overcome the semicircle brake(-holder) block that causes when self falls and the effect that makes extremely full at huge frictional force between the trig loop and dead point, so can make desktop be stabilized in the interior arbitrary height of range; Conversely, stumble and clamp the braking tongue by turning knob, the moving brake(-holder) block hook of the troughed belt of unblanking, can drive the gear teeth (19), tooth bar (21) motion easily, interior pipe (16) is with tooth bar (21) free lifting, and table frame (2) is free lifting thereupon also.
When adjusting the angle of inclination of desktop, only need the tight knob of rotary self-locking (8) gently, concentric gear (9) i.e. is and then rotation, and drive travelling gear (10) rotates, driving the gear (7) that is equipped with one heart on the lifter wheel (11) again by chain (12) rotates, because gear (7) meshes with the latch of tooth bar (5), therefore tooth bar (5) can free lifting when gear (7) rotates, tooth bar (5) is connected with (4) with support bar (3) by movable axis (6), the desktop front end can be propped up by support bar (3) and (4) like this, make desktop can reach any angle of inclination, as drawing and the drawing tables use, very convenient and practical.
